Meta has introduced NotebookLlama, an open-source alternative to Google’s NotebookLM, to turn documents into audio summaries. While NotebookLlama encourages developers to build upon its code for customizations, Google’s NotebookLM, released last year, recently expanded with business-focused features, positioning itself as a well-integrated, customizable tool for companies and professionals.
Google’s NotebookLM: Customization and a New Business Focus
Google’s NotebookLM, which began as Project Tailwind during Google I/O in June 2023, rolled out enhancements on October 17, adding more control for users over AI-generated audio summaries. With a new “Customize” option, users can specify content areas for the AI to focus on, minimizing “hallucinations”—a common AI issue where the system might create inaccurate details. The feature, aimed at keeping summaries relevant, has become popular among researchers and educators using NotebookLM for academic or organizational insights.
At the same time, Google launched a business-oriented version of NotebookLM. Through this pilot program, participating companies get early access to tools for team collaboration, higher usage quotas, and personalized support, though pricing and full availability details remain undisclosed. Raiza Martin, leading the NotebookLM project at Google Labs, sees the business expansion as a way to refine NotebookLM for professional environments, using feedback from pilot participants.
Meta’s Open-Source Response: The Arrival of NotebookLlama
Meta’s NotebookLlama, positioned as a direct rival, provides an open-source alternative that developers can freely modify and share. Unlike NotebookLM, which uses professionally recorded voices, NotebookLlama relies on AI-generated speech through Meta’s Llama-3.1-70B model and TTS model Parler-tts, resulting in somewhat mechanical audio. Meta encourages developers to experiment with and refine the model’s output through GitHub, allowing for potential community-driven improvements that Google’s closed system does not offer.
For those lacking high-powered GPUs, Meta recommends using the smaller Llama 8B model, as the 70B model’s high memory requirements make it impractical for many setups. Vikas Sharma from Meta acknowledges the tool’s limitations but emphasizes that NotebookLlama offers an adaptable framework, letting users experiment to optimize audio results.
Google Expands NotebookLM with New Media Integration
Google NotebookLM’s latest updates now support video and audio files, extending its reach to YouTube and other media content. Users can link to YouTube videos or upload audio files like .mp3s, allowing the AI to create concise summaries from video or audio content in various formats. Notably, NotebookLM’s integration works with both manual and auto-generated YouTube transcripts, delivering summaries that appeal to researchers, educators, and content creators looking for efficient data extraction.
Google has expanded NotebookLM significantly since its December 2023 debut, with its language model, Gemini 1.5 Pro, enhancing functionality across diverse media. Initial response to these updates was positive, with users sharing summaries that resemble podcast conversations, thanks to NotebookLM’s dual AI “hosts”. These AI voices replicate conversational tones, engaging listeners with humor and a natural delivery.
Open NotebookLM: A Free Alternative from Singapore’s GovTech
Adding another option to the mix, Singapore’s GovTech data scientist Gabriel Chua released Open NotebookLM on October 3. This free, open-source tool uses Meta’s Llama 3.1 for language processing and MeloTTS for voice generation, allowing PDF-to-podcast conversion. Open NotebookLM, accessible on GitHub and Hugging Face, offers multi-language support and voice tone customization but does not provide extensive integrations like Google’s product.
Chua’s project stands out for its simplicity. Designed on Gradio’s interface, it caters to users without technical expertise, aiming to keep functionality straightforward. Unlike Google’s detailed summarization and clickable citations, Open NotebookLM focuses on converting text to audio, offering a viable, lightweight alternative to the more integrated features of NotebookLM.
Google’s Response to Open-Source Competition
The growing competition in AI audio summarization also reflects broader industry trends. A leaked Google memo in May 2023 proposed that the company might benefit from working with the open-source AI community instead of competing against it. The memo suggested that Google should consider sharing smaller language model weights, which could establish it as a collaborative leader. However, Demis Hassabis, head of Google DeepMind, expressed skepticism about this approach, asserting that Google’s proprietary research would keep it competitive.
